Is it safe to give my senior dog heartworm medicine if I'm late?

Most of the monthly oral preventatives have a wide safety margin. Heartgrad is very safe, so if that is the preventative you use, then a second dose will not be harmful. If you use a different medication, check with your veterinarian before giving another dose.

I would contact your veterinarian for specific advice for Kera, but I can give you the following information. The two ingredients in Sentinel are very safe and there is a moderate dosage range. You don't mention Kiera's weight, but depending on her weight, repeating Sentinel may still be within her dosage range even if you gave the Sentinel on the 28th. I would also ask your veterinarinan about when you purchased the Sentinel since that may help you determine (with the number of tablets you have left) if you gave her one last month or not. Finally, it is generally recommended to repeat heartworm medication if you are not sure you gave it since heartworms and intestinal parasites can cause significant disease. I hope that was helpful.

Rocky should be ok. Heartworm disease is in fact transmitted by mosquitos. Thankfully in your location during the time missed there are not that many mosquitos around. It can take 6 months to show up positive on the test so I would recommend testing in October of this year the latest. I wouldn't stress too much. You can look out for coughing and exercise intolerance. Just continue giving the medication monthly at this point. Here is a website for the Heartworm Association if you have questions. https://www.heartwormsociety.org/pet-owner-resources Thank you for using PetCoach.

No, there is no need to go to the vet for missing the dose. Your dog should be fine. SHould there be microfilariae present, the next dose you gave should kill them. Just keep giving the heartworm medication as prescribed. Your dog will need a heartworm test anyway every year. No worry!

If you only missed 1 month, you should be fine. Just resume Heartgard right away . If you just want peace of mind, then you can have Lilly retested in 6 month from now; however, the chances of infection are pretty low. Thanks for visiting Petco Pet Education Center, formerly Petcoach and best wishes with your pet Lilly. Take care!

I am so sorry to hear about that. I think it will be fine to wait until Tuesday. A few days likely won't make a difference. I would talk to your vet though and let them to know to ensure they don't want to change their treatment plan any. Every vet clinic does heartworm treatment a little differently. I hope this helps.

Hi and thanks for using Petco Pet Education Center, formerly Petcoach! Ellie should be fine. Missing 3-4 days should not be a critical time period when talking about heartworm prevention. Now missing that dose over longer time periods could potentially cause a problem due to the life cycle of the heartworm and what stages the medicine kills, since the heartworm goes through several larval stages once inside a dog or a cat. The best thing to do in your case is exactly what you did, give the dose as soon as you realize you missed it and of course, contact your vet for their advice. Ellie should be fine. Great question though. I wish you the best of luck with her.
